To all whom it mag concern:

Be it known that I, MICHAEL PUSARESKI, a citizen of Russia, and residentof Lynn, county of Essex, Commonwealth of Massachusetts, have inventedan Improvement in Heel-Aflixing Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification,

like characters on the drawings representing like parts in each of theseveral views.

This invention is" directed to a machine for affixing heels to shoes andparticularly to a mechanism for securing heels to shoes by means ofscrews or like attaching means, as commonly practised in securing highheels of wood or the like to ladies shoes. A principal object of theinvention is to provide means operative rapidly and effectively in asemiautomatic manner to position accurately and hold secure the shoesole and upper with respect to the heel while the screws are forced intoplace, and in conjunction therewith to provide means operatlve rapidlyand reliably to drive the several screws home simultaneously. Theforegoing and other objects and advantages of the invention will morefully appear from the following detailed description, and thedistinctive features of novelty will be pointed out in the appendedclaims.

Referring to thedrawings: Figure 1 is a front view of a'machineconstructed in accordance with my invention with parts broken away; i

apart parallel guide ways 11, 11 formed with inturned flanges 11 to holdfor sliding movement two blocks 12, 13 which fit together and haveformed in their meeting sides cooperative portions of a heel seat 11.The guide ways 11 are shown as held to the platform 10 by clamp bolts 15which are passed through elongated slots 16 in lateral projections 17 atthe ends of said guide ways, this adjustment permitting said guide waysto be shifted laterally and adjusted accurately to position the heelsocket blocks 12, 13 correctly,'with respect to the operative devices tobe described. A stop plate 18 with an upturned front edge 18 isadustably clamped to the base to limit the forward movement of the block12 by means of a clamp bolt 19 which is passed througlr a pin 23engaging in a slot 24 of a lever arm 25which is fixed to a shaft 26horizontally j ournaled in the frame. This shaft has fixed at its outerend an operating handle lever 27 so that by' shifting this lever theblock 13 may be moved outwardly to first separate it from the block 12and open the socket 14: for the reception of the heel, and thereaftermove with it the block 12 to some little extent untilthe lever 27 comesagainst a fixedstop 27 a suitably positioned on the machine frame. .Atone side of the machine frame 10 is adjustably fixed an upright column28, the lower portion of this column having dovetailed slidingengagement with the frame as indicated at 28 and this column may beadjustably clamped to the frame in positionto locate the operatingdevices to be described correctly with reference to the heel seat justdescribed, by means of clamping bolts 29 which extend through avertically elongated slot 30 of the frame and through said column. Thecolumn 28 has a lateral bearing extension 31 extending out over theplatform 10* at some distance thereabove with an upward extension32extending up in parallelism with the upper end of the column 28proper. The lateral extension 31 has slidably guided therein a verticalrod 33 the lower end of which has pin and slot connection 34 with alever 35 fulcrumed to the frame at 36 and having link 37 pivoted to itsouter end which may extend down to a treadle (not shown). The rod 33 hasfittedthereon a compression coil spring 38 which presses upward againsta collar 39 fixed on said rod, the lower end of said spring reactingagainst the column extension 31, thus tending to keep the rod 33 andparts associated therewith elevated, The upper end of the rod33 hasfixed thereto a stout plate 40 which has fixed thereto spaced apartdepending presser bars 41, 41. These bars extend down to a pointrelatively near the platform 10 where their lower extremities areinturned toward each other as seen at 41 and have fixed at the endsthereof a presser head and templet 42. The purpose of the inturned barextremities 41 is to oermit them to extend down inside of the eel end ofthe shoe and the presser head and within the heel cavity of the shoe.the action of the spring 38 the presser head 42 is normally heldelevated some little distance above its operative position to which itis adapted to be depressed by operation of the treadle connection 37.The top portions of the column proper 28 and of the vertical extension32 are equipped with vertical guide ways 43 in which is slidabl fitted aframe 44 having horizontally ournaled therein a shaft 45. The shaft 45has fixed thereon a spur pinion 46 which meshes with a rack 47 fixed tothe extension 32 so that as said shaft 45 is turned the frame v44 willbe raised or lowered according to the direc tion of such turningmovement. The shaft 45 is equipped with a hand wheel or handle 48 and italso has fixed at its inner end a bevel pinion 49 which meshes with abevel gear 50 suitably journaled in the frame 44 having forthis purposeat its top a short stud extension 51 which fits into a socket in a topportion of the-frame and having at its bottom a shallow seat in whichfits a circular boss 52 extending up from the frame. The gear 50 is madehollow with aninternal gear 53 formed therein which meshes with aserles. of pinions 54, shown as three in numher and fixed at the tops ofa series of screw driver shafts 55. The pinions 54 are relatively thinor narrow faced as compared with the width of the face of the internalgear 53 so that said pinions will remain in Vmesh with said gearthroughout a short range of sliding movement with respect thereto. Theshafts 55 have fixed thereon bearing sleeves 56 which are slidablyfitted through the extension 31 as seen at 57 and compression coilsprings 58 are fitted on the shafts to press against-the tops 10f thesebushing sleeves with the other ends thereof ting nto threaded sockets ofsaid shafts.

The shafts 55 with: the screw driver. heads thereon are mounted in theslide frame'44 and guided in the fixed extension 31 in soaced apartrelation as required toen'gage the three screws which are usually driventhrough the heel seat of the shoe into the heel to secure the partstogether. 5 The presser head 42 is formed with templet holes 60 spaced aart according to the required spacing of t e screws, these holes beingof a size to permit the screws s to slip therethrough and the operativeend of the screw drivers to enter therein.

In use the presser head 42 being normall held elevated by the spring 38,the shoe r is applied thereto with the resser head fitting into the heelportion; hen the heel H is put into the then open sQcket14, the blocks12, 13, being then moved rearwardl r and spaced apart. Thereupon thetreadle 1s operated and the presser headv brings the v heel seat of theshoe down against the heel H, which it will be understood is at thistime mostly thereunder, though a little to the rear of its finalposition, Then the handle 27 is operated topress the blocks 13, 12forward and together, resulting'in sliding and pressing the heel Hforward closely against the small ledgeor lip L which is providedtherefor in usual practice, the shoe being at this time securely heldagainst dis placement by the presser head 42. Then while the treadle isstill held depressed to keep. the heel seat of the shoe firmly clampedto the heel, the hand wheel 48 is operated moving the slide frame 44downwardby the rack and pinion connection 46, 47 and at the same timethrough the described connections rotating the screwdriver shafts 55. Asthe rotating screw driver heads 59- the wide face of the gear 53,isjalso of ims:

portance in allowing for irregularities in the forward drive ofthe'screws as compared Wlth the downwardpositive feed 'of the 1 30 slideframe 44 and thereby it is insured that the screws will always be drivenin with a proper forward rotary movement without mutilating the threadhold in the wood. With the described mechanism the rapid and accuratepositioning and assemblage of the shoes with the heel is attained andthe securing elements may be applied simultaneously and much morerapidly than as at present practised. I am aware that the invention maybe embodied in other specific forms without departing from the spirit oressential attributes thereof, and I'there V fore desire the presentembodiment to be considered in all respects as illustrative and notrestrictive, reference bemg had to the appended claims rather than tothe foregoing description to indicate the scope of the invention.

Having described my invention, what I claim as new and desire to secureby Let ters Patent is:
